In this study, a numerical analysis is carried out to optimize the pin fins heat sink (PFHS) performance. The investigation is conducted by using Comsol Multiphysics v.5.4 software based on the finite elements method (FEM). The effect of the…

Unilateral renal agenesis is a congenital malformation characterized by the complete absence of one kidney. Megaureters, on the other hand, are urinary tract anomalies characterized by abnormal dilation of the ureters, resulting in obstruction of…

Since the beginning of the 1990s, a renewed interest for the thermoelectric appeared, due in particular to the emergence of environmental concerns regarding the gases used in refrigeration and emissions of greenhouse gases as well as the willingness…

Mixed convection is studied numerically to investigate the performance of the better heat transfer and also the effective cooling in a vented cylinder cavity, which is covered by two rotating discs. An external airflow enters the enclosure through an…

As part of this numerical study, we attempted to analyze the sliding and detachment of a vapor bubble after it grew on a heated plate in a convective flow. We then proceeded to simulate the sliding process and the detachment of a vapor bubble located…

Through this work, we want to evaluate the behavior of the fluid inside two successive chambers equipped with an opening for the fluid to enter the flow and the other for its exit. The fluid has a low temperature, while the lower wall of the two…

Low-grade heat from waste energy sources can be successfully recovered to produce power by an organic Rankine cycle. In the present work, reheat ORC is studied with three different wet organic fluids. The performance of R1270, R152a, and Cyclopropane…

The solar chimney is a low-temperature power station generating electricity. The most important parameterizes the value of the air velocity along the chimney. A 3D numerical model is developed to estimate and analyze various parameters of the solar…

Energy consumption in residential buildings Algerian very high, especially during the summer season. A comprehensive approach to designing low-energy buildings reduces the size of mechanical systems to offset the additional cost of energy efficiency…

The present work is a numerical simulation of free convection heat transfer from H-shaped cross-section placed in square container. The work is accomplished by using the commercial code ANSYS-CFX. The studied parameters were the Prandtl and Rayleigh…
